Whenever a conventional planetary gearhead is mounted to a engine, the sun gear must be aligned to pay for runout error of the servomotor shaft. Without proper alignment, load is unevenly distributed over the planetary gears and the drive train operates less efficiently. Also, gear life could be shortened. These alignment changes require skills that aren’t normally obtainable in the field.
Achieving a larger speed reduction ratio requires a smaller sun gear diameter (or an exceptionally large ring equipment). This smaller sun equipment is usually integral with its shaft, which should be smaller aswell, thereby reducing its strength and its own torque or load capability.

Various kinds gear trains, including those with planetary gears, are commonly used to acquire this the best possible reduction ratio. Planetary gear trains provide high stiffness and low backlash (necessary for accurate operation), plus even load distribution (to acquire optimum torque). Some planetary variations combine external-tooth pinion-and-gear models with planetary gear sections to simplify installation and boost acceleration. These hybrid gearheads are described later.
A simple planetary gearhead has some limitations regarding simple installation, load capacity, and speed, which are related to the sun gear.

Generally, the designer usually obtains the ideal speed decrease ratio by matching the inertia of the electric motor and gearbox with the inertia of the driven load. This inertia complementing minimizes power reduction in the motor, making it run more efficiently.

Servo motors deliver precise control of placement, velocity, and acceleration in the closed-loop systems of servomechanisms. Servo motors require a servo drive – this uses the feedback data to exactly control the position of the motors path and rotation distance.
Cone Drive’s stainless steel precision motion gearboxes are created for sterile manufacturing conditions. The product’s smooth surface area and curved contour permits easy cleaning and bacteria-free surfaces, ideal for food processing and pharmaceutical applications. The product is designed and ranked to IP69k offering maximum security against contaminant ingress in addition to leak free operation.
Servomotor selection usually starts with the designer seeking to reduce the engine size by utilizing a gearbox to reduce speed and boost torque. Speed reduction allows fast acceleration and deceleration of huge loads utilizing a small, less servo motor and gearbox expensive motor.
